Atomic Method

The Atomic Method can be used to unclog the nozzle of your Ultimaker 2. It will clear the blockage by pulling dirt or carbonized material out of the nozzle from the top side. To apply the Atomic Method you don’t need need to disassemble the print head or hot end, which makes it very easy to use this method.

Tip: Besides using this method to unclog the nozzle, you can use the Atomic Method when switching to a material that requires a lower printing temperature. This way all residue from the previous material will be removed, helping to prevent blockages.
